Dear Hank & John

Are there any liquid planets? What should I know about tuberculosis? Do we eat rocks other than salt? Why do I like crickety leg rubbing? What do I wear to an orchestral Ratatouille event? How do I hide my birthday? Is 100^99 bigger or smaller than 99^100? How do full moons work?  Hank and John Green have answers! If you're in need of dubious advice, email us at hankandjohn@gmail.com.Join us for monthly livestreams and an exclusive weekly podcast at patreon.com/dearhankandjohn.Follow us on Twitter! twitter.com/dearhankandjohn
